What is the Wall Sit Timer?
Slide down the wall until your knees are around 90 degrees and the timer starts counting only while your position is good. If you creep up or sink too low the coach tells you.
It measures knee angle and thigh angle in 3D, so the camera can be beside or diagonal to you. Set a target time and get spoken milestones at 10, 20 and 30 seconds and every minute.
